Simply tap the “Mayday” button to be connected for free to an
Amazon expert who can co-pilot you through any feature by drawing
on your screen, walking you through how to do something yourself,
or doing it for you — whatever works best. Mayday is available
24 × 7, 365 days a year, and it’s free. Throughout the process, you
will be able to see your Amazon Tech advisor live on your screen,
but they won’t see you. 15 seconds or less is the Mayday response
time goal.

Simply amazing, if it works as promised. Not sure how something like this could scale for tens of millions of customers, though.
